How fast do Azaleas and Hibiscus bushes grow?

I got flowering bushes for Mom's day and I'm curious how fast they grow. We live in Northern IL. Both bushes are hardy to -30 degrees F.





Azalea, now about 2 1/2' tall will mature to 7' tall 5' wide.





Hibiscus, now 2' tall, will mature to 6' tall and 8' wide.


Will Hibiscus only bloom in spring?

How fast do Azaleas and Hibiscus bushes grow?
You will find that azaleas are slow to moderate slow growers in northern IL. Hardy Hibiscus or Rose of Sharon is a medium rate grower. It blooms in late July/early August into Sept. Rose Mallow or perennial, herbaceous Hibiscus also blooms July-Sept.


Hibiscus plant when does it bloom and what does it need for care?

i planted one last season, is it time for it to bloom? i live in gary, ind....are my temperatures in this area good for this plant?

Hibiscus plant when does it bloom and what does it need for care?
Hibiscus plants ususally don't flower until mid to late summer. Since they are more tropical plants, they like the warmer weather. If it is a perennial hibiscus and is one for your zone, then it should be ok. Give it until atleast June for it to bloom, if it hasn't then it's probably dead. Usually, if it's not a perennial, it needs to be brought in during the cold winter months. I found that out the hard way when I had one planted in a pot and just covered it instead of bringing it in over the winter(I live in Northern Wisconsin). I waited until June or so and it never came back. All I had was some brown sticks in a pot.





As for care of it, just make sure its waterd well, but just don't over water it. Once the flowers die, just dead head them(picking off the dead flowers). The flowers will only last 2 days or so but will continue to bloom throughout the summer and into fall. Picking off the dead flowers will help the new flowers bloom and become bigger. Hibiscus flowers over time can get quite large but are pretty to see.
Reply:If you are talking about the Hibiscus shrub that is often referred to as Rose of Sharon, it does well in my zone 4 garden.





It is the last shrub to develop leaves and often looks dead at the beginning of the season sometimes into late June, but the beautiful fall flowers are worth it.





I have added it to a shrub border where the bareness of the branches are hidden by other plants.


What are the little black specks on my new Hibiscus house tree?

Had the tree 1 1/2 days. Had 5 blooms yesterday, tonight I saw lots of small black specks on the flowers that I think may be some kind of bug that I need to treat. With what?

Try dish soap diluted in water and spray it on the plant.

My hibiscus plant has stopped flowering . wat can i do for it at home without spendin much. i am in india?

In general-- hibiscus flower on new growth-- therefore, if you cut it back-- give it some fertilizer, it will put out new growth and it may bloom again.


good luck

Decent makeup brands

Bubbly growth on Hibiscus leaves gradually spreading, what can I treat this with?

fungicide?


Hibiscus plant question?

my hibiscus plant did not bloom since I bought it in 2 years, inside the house. Should I leave it outside during summer time to get flowers?

Hibiscus plant question?
It needs to go outside for the summer. I drag mine out every summer which seems like a pain but well worth it after it starts blooming. If you decide to take it outside, you should change the soil too, and maybe a new pot? Hibiscus will love you for the extra care
Reply:Hibiscuses go dormat when in a house becuase the temperatures in the house are like winter in the tropics. In places such as California and Florida the hibiscus will stop blooming in the winter and lose some leaves because the temperatures are only in the low 70s. They need mid 80s and full sun to bloom. It is normal for it not to bloom in the house, unless in a warm area you will only see scattered blooms inside if any at all.





This summer take it outside in full sun and it will bloom nicely. Also add some plant food so it can get started, it will take a month outdoors before it blooms. Must be warm outside too.
Reply:Absolutely, they really flourish in the ground or in a very large pot with good sunlight.
Reply:it needs light.
Reply:yes, it likes sun.


My tropical hibiscus needs help?

altho it is still blooming, the leaves are turning yellow and falling off.Is this normal or is there a problem?

My tropical hibiscus needs help?
hi


Mine just started doing that also, all of sudden. I live in California and also asked the same question about a week ago. I stopped watering it, I was watering it every other day, because it has been soooo hot here, I also just fertilized it and have just been giving it a good watering once a week. I have other Hibiscus close by and they are fine, but I only water them every two weeks. So I think my problem was over watering. It's either to much or to little.. Good luck , and let me know how it goes for you.
Reply:Maybe too wet or improper drainage?
Reply:Indoor hibiscus are very suseptable to Spider Mites, especially in dry air, which will cause the leave to yellow and fall because they feed on the plant.


Look closely where the leaves attach to the stem /trunk and see if there are tiny fine webs. The spider mite is very tiny and usually redish colour.


If you find this is the case, remove the plant immediately from the others and use a soap based insecticide repeatedly and hope you can save the plant.


Meanwhile mist your other plants and even create a pebble tray for the pots to sit in. The pebbles will keep the roots out of the water while the water in the tray will evaporate and increase the humidity around the plants and thus discouraging Spider Mites who love it hot and dry.
Reply:Actually this could be because of several factors. First understand that all plant roots need more oxygen than they do water. If the soil is too compacted, the roots will die. If the roots die, the plants die.


On the other hand it could be a lack of an essential nutrient...you could be experiencing something known as chlorosis, and my guess is you have a nitrogen deficiency.


My last guess would be water....make sure the soil is moist. When a plant has a lack of water and is begining to die...it will promote the fruits and flowers otherwise known as the reproductive parts of the flower. The plants intitial reaction is to save the seeds, save the babies...so it sends all the nutrients and water to the fruits and flowers...it drains the leaves of water and nutrients...thus the leaves turn yellow and fall.


So check all of those factors.
Reply:We experience this chlorosis and defoliation in the greenhouse when the plants have been producing lots of flowers and have not been watered sufficiently. If your plant is potted and has been heavily flowering, it is surely very root bound (Not a bad thing for forcing flower) and will need to be watered and fed lots more than if it were planted in a bed. We water, heavily, daily and feed at least once per week. The plants all have at least a half day of unbroken sunshine, too.


On the other hand, if your plant has been sitting too wet, it is likely losing nutrients due to leaching. This is unlikely if the plant is potted.

Reply:Could be dry or may need an acid soil water regularly if the former or add ericacious compost if the latter.
